Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 3 generators on 24 points:

(1,2)(3,5)(4,6)(7,8)(9,10)(11,17)(12,20)(13,16)(14,19)(15,21)(18,22)(23,24);(1,3)(2,5)(4,7)(6,8)(14,17)(15,20);(5,8)(9,11,12,18)(10,14,15,22)(13,19,21,24)(16,17,20,23)

Polycyclic presentation:
